jet question?

[blastermaster01]

when i got my cr80r it had a 125 main jet (stock size) in it. the previous owner did not jet for the mods. it has the mods in my sig. We put a different carb in it with a 150 main, it fouls plugs and we're running a lean mixture so the jetting is off. what size do i go to?

whats the color on the plugs when it fouls them

then your running really rich lol. the color of the plugs should be a nice brown cardboard.
try going down a size or two on your main.

Yeah i knew i was running rich lol. I just didn't know to go down or up in sizes. The 150 is in it now. Do i go back to the 125, (stock) and then go down from there? or go down from the 150

 

[blasterdude14]

what size carb is in it now. and just go down one size at a time form the 150 thats in there now
